There are just a few days left until Samsung's Unpacked event at Mobile World Congress in Barcelona, but rumours about the Galaxy S5 are showing no signs of slowing down.

Samsung fan site SamMobile on Monday reported that Samsung's next flagship smartphone will include a fingerprint sensor. Pocket-lint, meanwhile, citing Holland-based e-retailer Typhone, said the Galaxy S5 will sport a 5.2in full HD screen, as well as a 16-megapixel camera.

Samsung already revealed plans to shake things up with its next smartphone launch, announcing in January that "the display and the feel of the cover" will be different from its predecessors. Those changes were put on display last month when leaked photos of the allegedly re-designed home screen hit the Web.

Posted by tipster @evleaks, the images showcased a new home screen reminiscent of Microsoft's Windows Phone and Google Now cards, but equally sized and stacked atop one another.

But it appears Samsung may have taken a cue from another competitor, as well: SamMobile "confirmed" that the GS5 will come with a fingerprint sensor embedded in the home button, much like Apple's iPhone 5S.

"We would also like to confirm that Samsung hasn't opted for on-screen buttons and is still using physical buttons, like it has been using in the past on all of its flagship devices," the site said.

The sensor will reportedly work in a swipe movement, meaning the user would have to move their entire finger up or down the key to register the print. Apple, meanwhile, requires the owner to simply hold a finger onto the home button.

Meanwhile, reports of a 5.2in screen and 16-megapixel camera run contrary to previously leaked images of a box that said the phone will have a 5.25in, 2,560 x 1,440 screen and 20-megapixel camera, according to Pocket-lint.

A Samsung spokeswoman declined to comment on the MWC rumors.

Early this month, the tech giant sent invitations to its latest Unpacked event, which is expected to include the launch of the Galaxy S5. The event, set for 8 pm local time (7 pm GMT) on 24 February in Barcelona, will be streamed live online. ITProPortal will also be in the audience to report on the action.
